Hi,
I'm an IT from the University of Rome (La Sapienza) and actually I'm working
at the department of neurology. We've got a lot of trouble using fsl
(expecially the tbss software). I have tried to set up tbss on debian (etch
and lenny) and ubuntu (feisty and gutsy) using official and unofficial
packages (Michael Hanke).
In every machine (32 bit) we have:
- fsl package from your repository
- fsl-atlases from your repository
- fslview from your repository
- itk manually dowloaded and installed under /usr/local
- . /ect/fsl/fsl.sh globally set in /etc/bash.bashrc
- itk binaries in PATH (should we need a license for this ?)
- /bin/sh is a symbolic link to /bin/bash (NOT dash)
tbss_1_preproc CON_N00300_dti_data_FA.nii.gz CON_N00302_dti_data_FA.nii.gz
seems to work (it creates hdr and img files under FAi directory and moves
nii files under origdata).
tbss_2_reg -T seems to have problems (the process runs just for few seconds
and two empty msf files are created under FAi directory:
CON_N00300_dti_data_FA_FAi_to_target_nonlinear.msf and
CON_N00302_dti_data_FA_FAi_to_target_nonlinear.msf).
Finally, tbss_3_postreg -S crashes with this output:
/usr/lib/fsl/tbss_3_postreg: line 96: cd: FAi: No such file or directory
using pre-chosen target for registration

now view mean_FA_skeleton to check whether the default threshold of 2000
needs changing, when running:
tbss_4_prestats [threshold]
Is this a sort of bug ?
Thank you for your help.
